Table S6. Loci table

Descriptive statistics for the seven molecular loci used to construct phylogenetic relationships among S. varius, S. castaneoventris, S. owstoni, and S. olivaceus. The summary includes the length of the sequences (in base pairs), the number of alleles, the number of segregating sites (s), the number of parsimony-informative sites (PI sites), nucleotide diversity (π), and the nucleotide substitution model. Statistics are drawn from ingroup sequences only. Note that ND2 statistics are drawn from a reduced ND2 alignment, which comprised the 16 samples sequenced for nuclear loci.本数据集针对用于构建S. varius、S. castaneoventris、S. owstoni及S. olivaceus系统发育关系的7个分子位点（molecular loci）开展描述性统计分析。本次统计汇总内容包括序列长度（单位：碱基对）、等位基因数量、分离位点（segregating sites，缩写为s）数目、简约信息位点（parsimony-informative sites，简称PI位点）数目、核苷酸多样性（π）以及核苷酸替换模型。所有统计结果均仅基于内群序列（ingroup sequences）计算得到。需注意，ND2的统计结果源自简化后的ND2序列比对集，该比对集包含了针对核位点完成测序的16份样本。
